SYNOPSIS
The duality between the capacity regions of Gaussian broadcast channels and multiple access channels plays an important role in proving the capacity region of Gaussian vector broadcast channels with private messages. In the first part of this talk, we briefly introduce a new method for proving the optimality of Gaussian inputs. In the second part, we introduce some of the results we obtained on the duality between the capacity regions of discrete broadcast channels
and multiple access channels.

 

ABOUT THE SPEAKER
Dr Yanlin Geng received his B.Sc. (mathematics and applied mathematics) and M.Eng. (signal and information processing) from Peking University, and Ph.D. (information engineering) from the Chinese University of Hong Kong respectively.
Dr.Yanlin Geng is mainly interested in some mathematical problems arising in signal processing and network information theory. Since 2009, he has been focusing on the broadcast channel. Recently he is also working on optimization problems in models with additive Gaussian noises and discrete channel models with symmetric outputs.
